The best rule is to say nothing. The regulatory bodies have handled this for us and we should say nothing more than that they need to be obeyed. Delete word "safety" in this sentence. Also delete the paragraphs "Flicker can cause... [B38].", "It is suggested... and upper cut- off frequencies.", and "This standard does not specify... [B38]." Recommendation/Instruction to editor -There are two eye/skin safety issues related to VLC regulations:

If the first bit is kept, then add a space in "VLC regulations:", otherwise, rewrite this with a list of references regarding the regulations in this band. In that case, it should be bibliography references to regulatory documents, not scientific studies. Recommendation/Instruction to editor -Delete bibliography references such as -Flicker is an impression of unsteadiness of visual sensation induced by a light stimulus whose luminance or spectral distribution fluctuates with time [B47]. The flicker threshold frequency (CFF, a.k.a. flicker fusion threshold) is the frequency at which an intermittent light stimulus appears to be completely steady to the observer. Flicker may cause harmful health impacts: visual discomfort [B44], eyestrain [B43], headache [B45], increase in speed and decrease in performance of mental tasks (reading comprehension) [B42], repetitive behavior of autistic children [B40], and photosensitive epilepsy (2% of all epilepsy cases) [B38]. -It is suggested that the flicker due to VLC transmission not fall within the modulation frequency region defined by a lower cut-off frequency (onset of photoepilepsy) [B38] and an upper cut-off frequency (highest frequency for ecr responses) that is, a device compliant to this standard should not exhibit modulation rates between these lower and upper cut-off frequencies. -This standard does not specify flicker nor light intensity; rather, the reader is referred to the following references:[B37] [B38].

Roberts Annex I 301 (SY) This annex is empty Annex I is currently blank Fill the annex or delete the annex. In the document we have Annex B.2 which is called "Regulatory documents" and we have Annex I which is called 'VLC Regulatory Annex". We don't need both. Suggest we delete Annex I and keep Annex B.2. Recommendation/Instruction to editor -Same as CID 190 -Add local and regional regulations to Annex I from IEEE P802.15-09-0202-03-0007 VLC Regulation Document Configuration
